LO likely has shingles, which could spread as chicken pox to anyone who hasn't had chicken pox or gotten the chicken pox vaccine. I haven't had chicken pox or the vaccine. I'm going to get a blood test to see if I have immunity, but in the meantime, does anyone have experience with exposure to the chicken pox virus during pregnancy (and not immune)? I called my OB but the nurse was not very helpful besides suggesting I come in for a blood test.
